Filter by:During the last 25 years, OCT has become one of the most common imaging technologies used to diagnose and monitor retinal diseases, including AMD. The OCT self-imaging capabilities of the Notal Vision Home OCT (NVHO) system for retinal fluid visualization in the central 10 degrees were validated during several prospective clinical studies1,2,3,4,5. This study is designed to evaluate the retinal fluid exposure of eyes with NV-AMD, using the NVHO system to guide therapy.
Comparison of high-resolution optical coherence tomography (High-Res-OCT) to conventional imaging modalities for the diagnosis of eye diseases
Although the safety and efficacy of bevacizumab has been established in several phase 3 trials, there is only little documented about the long-term safety and efficacy in the 'real-world practice' in large populations from different regions. Therefore the investigators evaluate the long-term safety and efficacy of intravitreal treatment with bevacizumab by registration of best corrected visual acuity, side-effects and central retinal thickness as measured with the ocular coherence tomography if available. This will allow the investigators to compare the results of their centre with the results of several phase 3 trials from the literature and will guide improvements in their treatment protocols.
Background/aims: Aflibercept is an approved therapy for neovascular macular degeneration (AMD), diabetic macular edema (DME), retinal vein occlusion and other retinal conditions. Ziv-aflibercept is also approved by FDA and is extremely cost-effective relative to the expensive same molecule aflibercept. In vitro and in vivo studies did not detect toxicity to the retinal pigment epithelium cells using the approved cancer protein, ziv-aflibercept. Ziv-aflibercept had no loss of anti-VEGF activity when kept at 4°C in polycarbonate syringes over 4 weeks. Similar to bevacizumab, compounded ziv-aflibercept would yield a tremendous saving compared to aflibercept or ranibizumab. Phase I studies and case reports did not report any untoward toxic effects but attested to the clinical efficacy of the medication. Our purpose is to ascertain the long-term safety and efficacy in various retinal diseases of intravitreal ziv-aflibercept. Methods: Prospectively, consecutive patients with retinal disease that require aflibercept (AMD, DME, RVO, and others) will undergo instead the same molecule ziv-aflibercept intravitreal injection of 0.05 ml of fresh filtered ziv-aflibercept (1.25mg). Monitoring of best-corrected visual acuity, intraocular inflammation, cataract progression, and retinal structure by spectral domain OCT to be done initially, one month, 6 months, 1 year, and 2 years after injections. Anticipated Results: Analyze signs of retinal toxicity, intraocular inflammation, or change in lens status, together with best corrected visual acuity and central foveal thickness at 1 month, 6 months, 1 year and 2 year. Anticipated Conclusions: Off label use of ziv-aflibercept improves visual acuity without ocular toxicity and offers a cheaper alternative to the same molecule aflibercept (or lucentis), especially in the third world similar to bevacizumab.
The purpose of this study is to evaluate the clinical results of anti-VEGF intra-vitreal injections (IVT) in CNV secondary
